The domes unite the different facilities. Constructed from modular steel frames with horizontal aluminium louvres they provide some shelter from the sun but allow cooling air to enter.

Two of the dome-like forms contain buildings. The largest covers a three-storey administration block for the sewage works while the smallest one contains a single building with a multifunctional space for use by visitors or for events.

第三个圆顶最高 ， 但内部并没有建筑 ， 而露天空间中设置有生态教育中心 。

同时 ， 其内部还有着三层楼高的平台 ， 人们可通过行政大楼屋顶的螺旋楼梯或人行道进入 。

The third dome which is the highest does not contain a building. The open-air space accommodates the ecological educational centre.
